Abstract
The utility model discloses a fixed pulley device provided with a safety hook and relates to the technical field of pulley devices.The device comprises a fixed pulley, the safety hook and a lifting rope, wherein the lower end of the safety hook is fixedly connected with a connecting rod via a fastener, the connecting rod is fixedly connected with the top end of the fixed pulley via a fastener, and the lifting rope penetrates through the upper pulley surface of the fixed pulley.According to the device, since the safety hook is additionally mounted, falling of the fixed pulley can effectively avoided in a use process, and the device is low in manufacturing cost, easy to operate, and safe and reliable to operate, is successfully used many times in a task field, and has a good effect and great popularization prospects.
Description
Technical field
The utility model relates to a kind of pulley gear technical field, relates in particular to a kind of fixed pulley with auxiliary catch.
Background technology
Transmit up and down in the operation process of Work tool and material at steel tower, the use of fixed pulley is very general.Fixed pulley originally relies on the common cast iron hook in one of top to be fixed on angle bar.Staff's movement range is large a little, touches cleek by mistake.Cleek just is easily deviate to fall from angle bar, initiation potential.
Utility model content
Technical problem to be solved in the utility model is to provide and a kind ofly can solves in use a kind of fixed pulley with auxiliary catch of obscission of fixed pulley.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of fixed pulley with auxiliary catch, comprise fixed pulley, auxiliary catch and lifting rope, described auxiliary catch lower end is fixedly connected with pipe link by fastener, described pipe link is fixedly connected with by fastener with described fixed pulley top, and described lifting rope is through the pulley upper surface of described fixed pulley.
Preferably, described auxiliary catch comprises camber hook, tommy bar, and described camber hook bottom is provided with tommy bar groove, and described tommy bar removably connects by pin and described tommy bar groove.
Preferably, the pulley of described fixed pulley inside is fixedly connected with by bearing pin.
The beneficial effect that adopts technique scheme to produce is: the utility model can effectively prevent that by installing auxiliary catch additional fixed pulley from use coming off, its cost of manufacture is low, easy operating, safety of operation is reliable, successfully use repeatedly at operation field, respond well, there is great promotion prospect.
Brief description of the drawings
Fig. 1 is the utility model integral structure schematic diagram;
Wherein, 1 camber hook, 2 tommy bars, 3 pipe links, 4 fixed pulleys.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the utility model is a kind of fixed pulley with auxiliary catch, comprise fixed pulley 4, auxiliary catch and lifting rope, described auxiliary catch lower end is fixedly connected with pipe link 3 by fastener, described pipe link 3 is fixedly connected with by fastener with described fixed pulley 4 tops, and described lifting rope is through the pulley upper surface of described fixed pulley 4; Described auxiliary catch comprises camber hook 1, tommy bar 2, and described camber is linked up with 1 bottom and is provided with tommy bar groove, and described tommy bar 2 removably connects by pin and described tommy bar groove; The pulley of described fixed pulley 4 inside is fixedly connected with by bearing pin.
The utility model, is replaced with cleek the cleek that carries insurance.In use, staff only need open hook insurance gently, and hook catches on angle bar, then decontrols insurance, and fixed pulley is just fixed on angle bar.Even if staff in the course of the work movement range is large a little, touch fixed pulley by mistake, the auxiliary catch of fixed pulley top also can work, and prevents that fixed pulley from coming off.
The utility model can effectively prevent that by installing auxiliary catch additional fixed pulley from use coming off, and its cost of manufacture is low, easy operating, and safety of operation is reliable, successfully uses repeatedly at operation field, respond well, has great promotion prospect.
